The Notebook Review forums were hosted by TechTarget, who shut down them down on January 31, 2022. This static read-only archive was pulled by NBR forum users between January 20 and January 31, 2022, in an effort to make sure that the valuable technical information that had been posted on the forums is preserved. For current discussions, many NBR forum users moved over to NotebookTalk.net after the shutdown.
Yes it can. In the US wireless channels 12 and 13 are typically not being used whereas the rest of the world does make a use of them but that doesn't really affect you.
Yeah, you should be able to run your router wherever you like. The only real concern would be if the wall plugs are correct, though I don't know what South Korea's plugs look like.
Channels can be configured in your router's settings. Think of it as (sort of like) different roads all going to the same place. Some roads (like Channel 11 or 12) might be crowded, so you could take a detour onto a different road (channel) to help improve performance.
Problems? See this thread at archive.org.
